BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an axial-flow fluid pressurizer, and more particularly to an axial-flow fluid pressurizer installed in a fluid flow.

2. Description of Prior Art

In a general water cooling heat dissipating apparatus, the flow rate of a fluid will be lowered due to factors like the location of electronic components at an end of a pipeline being near a water pump, the curvature of ducts, and the loss of kinetic energy between the fluid and internal walls of the ducts. As a result, the heat dissipation for the electronic components will become poor or even overheated and damaged. Thus, finding a way of improving the pressure and flow rate of the fluid for a fluid pressurizer has become an important subject for manufacturers and designers of the related industry.

A traditional fluid pressurizer includes a base, an opening disposed separately on both sides of the base and aligned orthogonally to each other, two joints coupled to the openings, a vane installed inside the base, a driving motor fixed onto the exterior of the base, and a transmission shaft protruded from the center of the motor and passing through the base to connect the vane, such that the transmission shaft of the motor can drive the vane to rotate.

The aforementioned traditional fluid pressurizer still has the following drawbacks in its application. Since the two openings are aligned orthogonally, the fluid will hit the internal wall of the base and results in a large loss of kinetic energy after the fluid enters into the pressurizer, and the effect of boosting the pressure will be very limited. Further, the driving motor provided for preventing permeations is installed outside the base, and thus the overall volume of the pressurizer becomes very large, not only having difficulties to be used in electronic products (or medical treatment products) with small interior space, but also causing a high cost and greatly lowering the practicability and economic effect of the pressurizer.

In view of the shortcomings of the prior art, the inventor of the present invention based on years of experience in the related industry to conduct experiments and modifications, and finally came up with a feasible solution by providing an axial-flow fluid pressurizer in accordance with the present invention to overcome the shortcomings of the prior art.

SUMMARY OF THE INVENTION

Therefore, the present invention is to overcome the foregoing shortcomings and avoid existing deficiencies by providing an axial-flow fluid pressurizer that employs a rotor shaft installed in a pipe to greatly improve the pressure and flow rate of a fluid without consuming the kinetic energy of the fluid.

The present invention provides an axial-flow fluid pressurizer that comprises a pipe, two connecting bases, a rotor and a stator. The pipe has two openings for connecting the connecting base. The connecting base has a shaft base inside the connecting base, a plurality of support arms coupled to the shaft base and an internal wall of the connecting base, and a through groove between the support arms. The rotor is contained in the pipe and disposed parallel to the axis of the pipe. The rotor has a revolver and a magnet element coupled to the revolver. The revolver has a protruding shaft disposed separately on both ends and embedded into the shaft base. The stator is disposed around the pipe and corresponding to the rotor for driving the rotor to rotate with respect to the stator by the interactions of magnetic excitation and increase the pressure and flow of the fluid without consuming the kinetic energy of the fluid.

DETAILED DESCRIPTION OF THE INVENTION

The technical characteristics, features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings. However, the drawings are provided for reference and illustration only and are not intended for limiting the scope of the invention.

Referring to FIGS. 1 to 3 for an exploded view, a perspective view and a cross-sectional view of the present invention, an axial-flow fluid pressurizer of the invention comprises a pipe 10, two connecting bases 20, a rotor 30 and a stator 40.

The pipe 10 is a circular vertical pipe having an opening 11, 12 disposed separately on both upper and lower ends of the pipe 10, and an internal screw thread 13 disposed on an internal surface of each opening 11, 12.

The connecting base 20 is connected separately to each opening 11, 12 of the pipe 10 and includes a joint 21, an extending ring 22 protruded downward from the bottom of the joint 21, and an external screw thread 221 disposed at the external periphery of the extending ring 22 for connecting the internal screw thread 13 of the pipe 10. The extending ring 22 forms a shaft base 23 therein, and the shaft base 23 is connected to an internal wall of the extending ring 22 by a plurality of support arms 24, and a through groove 25 is formed between the support arms 24. Further, a flange 26 is protruded outward from a position between the joint 21 and the extending ring 22 for attaching distal surfaces of each opening 11, 12 of the pipe 10.

The rotor 30 is disposed in the pipe 10 and parallel to the axis of the pipe 10. The rotor 30 includes a revolver 31 and a magnet element 32, and the revolver 31 can be made of a plastic material or a ceramic material and installed according to the properties of different fluids. The revolver 31 has a protruding shaft 311 protruded separately from both ends of the revolver 31 and embedded correspondingly in the shaft base 23 of the connecting base 20. The revolver 31 at its exterior forms a plurality of spiral vanes 312 for boosting the pressure of the fluid, and the magnet element 32 can be a circular or cylindrical permanent magnet (not shown in the figure). In this embodiment, the magnet element 32 is comprised of a cylinder 321 and a plurality of magnetic pole plates 322 disposed with an interval apart from each other and around an external periphery of the cylinder 321.

The stator 40 is disposed around the exterior of the pipe 10 and corresponding to the rotor 30, and the stator 40 includes two silicon steel rings 41 and a coil module 42, and each silicon steel ring 41 has four arc plates 411 disposed with an interval apart from each other inside the silicon steel ring 41, and the coil module 42 is installed at an external periphery of each plate 411, and the plates 411 of each silicon steel ring 41 are installed alternately, such that when the coil module 42 is electrically conducted by a current, the interactions of magnetic excitation will drive the rotor 30 to rotate with respect to the stator 40.

Referring to FIG. 4 for a schematic view of the use of a heat dissipating apparatus of the present invention, the assembly of the foregoing components can connect each joint 21 of the connecting base 20 with a soft tube of a water cooling heat dissipating apparatus (not shown in the figure). If a coolant is introduced into the soft tube for the use of the fluid pressurizer, and a coil module 42 of the stator 40 is electrically conducted by an electric current, and the coolant is guided to the connecting base 20, the rotor 30 will be driven by the stator 40 to rotate, and the pressure and flow rate of the coolant will be increased greatly without consuming the kinetic energy of the coolant by means of using the vane 312 of the revolver 31 to guide the coolant and installing the rotor 30 along the axis of the pipe 10.

The present invention is illustrated with reference to the preferred embodiment and not intended to limit the patent scope of the present invention. Various substitutions and modifications have suggested in the foregoing description, and other will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
